Ask HN: Why Don't People Wear Masks For Pollution in Delhi?

Yesterday Delhi's ambient concentrations of fine particulate matter (PM2.5) breached 800 micrograms/cubic meter according to real time data collected by the Delhi Pollution Control Committee.

As far as I am aware, no schools were closed, and I don't see anyone wearing masks. In Shanghai the public has been much more responsive and has voiced concerns regarding poor air quality.
